There were two clowns, if I get it right. The mask-wearer and the lip-tickler.
The lip tickling worries me. It takes us back to the days of Uncle Remus.
Twain/Clemens could deconstruct all this...
Let's entertain the possibility that there was racist intent. There's no statement of events which demonstrates that's true but for our purposes say it's not impossible. Wouldn't reason suggest that something substantial be the proof? If idiots were automatically racist we'd be knee deep in blood.
Also let's pick a fictional blue race and call them bleems so we have less emotional baggage for an analysis.
Now Bleems have been persecuted in the past and there is discrimination ongoing on occasion. Further, let's remove famous politicians from this because hackery is will select most any situation for advantage. So the Bleem in question is a famous Shakespearian actor who only does plays in Klingon. In fact he's regarded by some fans as the finest of his day.
Sadly, there is a group which in the past who has persecuted Bleems to the point of murder. They are of green majority race, the Skyrons.This organization has had those fangs pulled but clearly they possess all the hatred from those days.
Someone intentionally mocks the bleem actor and being blue is some part of the reason for it. Maybe. In any case a common thing is done which is to lampoon actors by exaggerating physical features. That meant the mask was exaggerated. Tasteless perhaps but that hardly means the wearer intends to abuse bleems, but news sensation sells in this world to. The emotional statement was pushed and that would be that but Shakespeare is serious stuff. The two main divisions are those who want it in Klingon and those who do Romulan only. Some members of each group are openly hostile to criticism and despise the other side.
Well...
On their Wide World Sponge there is a computer forum which has a part for Shakespeare and News.
One fellow loves this stuff and it's Klingon or wrong. Little Bongo we'll call him. He has a few dominating concerns he posts about. One is how racist Skyons who favor Romulen are and defending his favorite actor. So he sees the opportunity to use an emotional statement devoid of any factual basis to make the actor a victim. The possibility that perhaps the real motivation is that the "racist" doesn't like the acting is dismissed. He had supporters like The Savage Testicle who also indulges in excessive hyperbole.
Other members like Ridiculously Fast Motorcyclist finds the shameless opportunistic mentality to be the most offensive thing, being all to common.
When someone must be a racist for not liking Shakespearian Klingon or bad actors then somethings amiss.
